The problem is, lots of companies are taking advantage of our do-good intentions and making some not-so-green products look planet friendly. The practice is called "greenwashing," and according to The Seven Sins of Greenwashing, it's on the rise.

Here are the seven sneaky "sins" we're falling for, according to the site:

Sin of the Hidden Trade-Off.Suggesting a product is green based on an "unreasonably narrow" set of attributes. Paper from a sustainably harvested forest, for example, is not necessarily environmentally preferable. Other environmental issues in the paper-making process—including energy, greenhouse gas emissions, and water and air pollution—may be equally or more significant.

Sin of No Proof.Making a claim that can't be easily substantiated. A common example is toilet paper that claims to be made with a certain percentage of post-consumer recycled content without any evidence or a reliable third-party certification.

Sin of Vagueness.Making a claim that is likely to be misunderstood by consumers. "All-natural" sounds nice, right? Until you consider that arsenic, uranium, mercury, and formaldehyde are all naturally occurring—and all poisonous.

Sin of Irrelevance. *Making a claim that may be truthful but is unimportant or unhelpful. *Plenty of products are labeled "CFC-free," for example. But CFCs have been illegal for decades, so all products are (or should be!) CFC-free.

Sin of Lesser of Two Evils. *Making a claim that distracts consumers from greater environmental issues. *Organic cigarettes, anyone?

Sin of Fibbing.In a word: lying. Thankfully, this is the least frequently committed sin. The most common examples were products falsely claiming to be Energy Star certified.

Sin of Worshiping False Labels.Giving products fake labels or claims of third-party endorsement. A brand of aluminum foil, for example, bears a "certification" label—from the company's own in-house environmental program.

I'm guilty of an even stupider sin: Buying products with "natural" looking packaging that are packed with nasty ingredients. D'oh!

So what's a savvy shopper to do?

The site says to look for products with the following legit certifications:

Do you guys try to buy things that are "green"? And what: Makeup? Clothing? Food? Do you trust manufacturers' claims? Or do you read packaging more closely? What do you look for when you want something that's environmentally friendly? Or are you just bored by the whole "green" thing?
